the device comprises a drying box body, a separating box body, a material outlet, a first roller, a square plate, a sliding plate, a bearing sleeve, a lead screw, a fixing plate and a crushing plate, wherein the separating box body is fixedly arranged right above the drying box body and is in a funnel shape, the material outlet is arranged at the bottom of the separating box body, one end of the separating box body is rotatably connected with the first roller, the first roller is driven by a motor, the square plate is fixedly arranged on two sides of the separating box body, the sliding plate is fixedly arranged on two sides of the upper inner wall and the lower inner wall of the square plate, the bearing sleeve is connected between the two sliding plates in a sliding manner, one end of the bearing sleeve is rotatably connected with the lead screw, the lead screw penetrates through one side of the square plate, the bearing sleeve is sleeved on the second roller, a first filter cloth is sleeved between the first roller and the second roller, the first filter cloth is obliquely arranged between, the filter screen plate is contacted with the lower end of the first filter cloth, the other end of the top of the separation box body is fixedly provided with a slag discharging box, and the slag discharging box is positioned right above the part, extending out of the drying box body, of the second filter cloth;
the solid-liquid separation device comprises the following working steps: pouring the excrement on the first filter cloth, separating liquid from solid through the filter screen plate and the first filter cloth, discharging the liquid from a discharge outlet, driving the motor to drive the first roller and the second roller to rotate so as to drive the first filter cloth to rotate, smashing the solid through the smashing plate in the process of conveying the solid through the first filter cloth, discharging water in the solid, draining the water in the smashed solid through the obliquely arranged first filter cloth, conveying the smashed solid to the residue discharge box through the first filter cloth, discharging the solid onto the second filter cloth, driving the electric telescopic rod to stretch until a gap exists between the third filter cloth and the second filter cloth, driving the third filter cloth to rotate through the fifth roller and the sixth roller, driving the second filter cloth to rotate through the third roller and the fourth roller, extruding the water in the smashed solid through the third filter cloth and the second filter cloth when the second filter cloth conveys the smashed solid, extruding the water in the smashed solid, and simultaneously driving the hot air blower to dry the smashed solid, scraping off the residual dried solid of the second filter cloth by a scraper, discharging the dried solid by a residue discharge funnel, conveying the dried solid to a solid fertilizer making machine for making a solid organic fertilizer, and introducing the liquid into a liquid anaerobic fermentation tank for fermentation;
step two, performing fermentation treatment on the liquid in a liquid anaerobic fermentation tank, feeding the fermented biogas into a biogas collecting tank, feeding the prepared biogas slurry into a biogas slurry collector, and feeding the prepared biogas residues into a biogas residue collector;
step three, sending the biogas from the biogas collection tank into a generator to generate electricity, and merging the generated electricity into a power grid; feeding the biogas residues from the biogas residue collector into a fertilizer making machine for making a solid machine fertilizer, and feeding the biogas slurry from the biogas slurry collector into an irrigator in the cress cultivation pond for irrigating cress finished seeds on the floating bed;
the processing steps of the finished cress seeds are as follows:
(1) drying the cress seeds for 1-2 days, then putting the seeds into clear water for rinsing to remove shrunken seeds, leaving full seeds, soaking the full seeds in the clear water for 8-12 hours, then fishing out, and draining off excessive water until the full seeds do not drip water;
(2) weighing 200g of coating agent and 5.0-8.0 kg of soaked seeds, placing the coating agent in a round-bottom plastic basin, slowly adding the soaked and plump seeds into the basin while stirring until the coating agent is completely coated on the soaked seeds, airing for about 30 minutes for the day to obtain finished seeds, and uniformly broadcasting the finished seeds;
the manufacturing method of the floating bed comprises the following steps:
s1, firstly, hot-melting and connecting a plurality of PPR pipes by using hole pipe joints to manufacture a frame, respectively installing 2 polypropylene meshes on a middle frame and a bottom frame of the frame by using ropes, and installing 1 polypropylene mesh on peripheral frames of the frame by using ropes; and 1 piece of plant fiber non-woven fabric sheet is placed on the middle frame mesh sheet to obtain the floating bed;
s2, selecting the number of floating beds according to the area of the cress cultivation pool, wherein each row is a group and fixed in the pond, and a distance of 0.5 m is reserved between each two rows;
s3, manually scattering the treated cress finished seeds on a floating bed non-woven fabric cover;
the third step also comprises that the water purified by the cress is used for washing the pig farm after irrigation, and the obtained excrement is returned to the livestock excrement pool through a waste collector for next round of recycling;
the drying temperature in the first step is 80-130 ℃.
